The main door can be planned in the extreme ends of north side or east side of the flat, so that the north east corner is occupied with the main door in an east facing flat.

That means the door will be having good natural lighting and open for the entry of the Vastu energy. Also the north east corner will become weightless automatically. And the sun light will be flowing freely without any obstruction for the other places of the flat.

The door can be situated up to the center of the eastern wall of the flat. A door in the southern side of the eastern wall and at the extreme end of the south east corner is a bad one as per Vastu Shastra and must be avoided. A main door in the south east corner will bring bad luck and the people may suffer due to financial strains.
